Publication number: 20150147820Abstract: A system for managing bulk liquids for an automated clinical analyzer. The system comprises (a) at least one local reservoir for storing a bulk liquid for impending use, (b) at least one container for holding a bulk liquid before the liquid is transferred to a local reservoir, and (c) a controller for monitoring the level of a bulk liquid in a local reservoir. The local reservoir for storing a bulk liquid for impending use can be a trough. The use of troughs for storing a reagent, a diluent, or some other treating agent for impending use enables an aspirating/dispensing device having a plurality of pipettes to aspirate and dispense the reagent,diluent, or other treating agent at a high rate of throughput. The controller can monitor the level of a liquid in (a) a local reservoir for storing a bulk liquid for imminent use and the level of liquid in a (b) container for holding a bulk liquid before the liquid is transferred to a local reservoir.Type: ApplicationFiled: February 2, 2015Publication date: May 28, 2015Inventors: Patrick P.

Patent number: 9012236Abstract: The invention provides a system that can process a raw biological sample, perform a biochemical reaction and provide an analysis readout. For example, the system can extract DNA from a swab, amplify STR loci from the DNA, and analyze the amplified loci and STR markers in the sample. The system integrates these functions by using microfluidic components to connect what can be macrofluidic functions. In one embodiment the system includes a sample purification module, a reaction module, a post-reaction clean-up module, a capillary electrophoresis module and a computer. In certain embodiments, the system includes a disposable cartridge for performing analyte capture. The cartridge can comprise a fluidic manifold having macrofluidic chambers mated with microfluidic chips that route the liquids between chambers. The system fits within an enclosure of no more than 10 ft3. and can be a closed, portable, and/or a battery operated system. The system can be used to go from raw sample to analysis in less than 4 hours.Type: GrantFiled: August 15, 2013Date of Patent: April 21, 2015Assignee: IntegenX Inc.Inventors: Stevan B. Jovanovich, William D. Nielsen, David S. Cohen, Michael Recknor, Mattias Vangbo, Ezra Van Gelder, Omar El-Sissi
